LOADER.

A Application led August 17, 1925. Serial No. 50,679.

To all whomjz't may concern y Be it known that l, JOHN Girmi... a citizen of the United States, residing at Detroit, in the county of Becker and State of Minne- Sota, have invented a new and useful Loader, of which the following is a specification.

- This invention aims.- 'to provide novel means for handling material, and, particularly, to provide novel means .for removing material from a fork or bucket., as the bucket is raised. v l

It is within the province of the disclosure to improve generally and to lenhance the utility of 'devices of that type to which the invention appertains.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and .in

thel details of construction hereinafter dc' scribed and claimed, it being understood that l drained .and when the material is pushed :off

changes in the precise-embodiment of the invention herein disclosed, may be made ,within the scope or what is claimed without departing from .the spirit of the invention: In the drawings Figure 1 shows inside elevation, a device constructed in Az'iccordance'with the invention; Figure 2 is a top plan showing a portion of the boom andparts carried thereby; Figure 3 is an Velevation showing the, fork and attendant parts; Figure 4 is .a cross section on the line 4-4 of Figure 1; Figure 5 is a side elevation showing certain of the parts as they will appeark when the fork is the fork; Figure 6 is a side e evation showing a slight modification; Figure 7 is an lend elevationl of the-Structure depicted 1in Figure 6.

The device forming the/subject matter 'of this application may be applied to machines of widely 'ditlerentsorta but, by way of illustration, there is shown, in Figure 1, a support v'1, including a wheel-mounted truck 2 carrying a standard 3.- A turntable 'il is journaled on the truck 2 and is operated in any preferred way, for instance, by means of a worm wheel l5` on the turntable, the

worm -wheel meshing with. a worm 6-on a shaft 7 supported for rotation-on the truck 2. .The shaft 7 is driven fromla drum 8 jouring, `diagramntatieally,v

naled on the truck 2, the numeral 9; designatwhereby the shaft 7 may be coupled to the drum 8, and be uncoupled from the drum, at

-provided for operating any suitable means..

the will of an operator. There-'is an operative connection 10 between the drum v8 vand a l prime mover 11, on the truck 2, the lprime mover being a gasoline engine, oranything else adapted for the purpose. The machine comprises an inclined-boom A12 connected at its lower end to the turntable lin charge of the engine'll may reach the line 20 readily. Any desired mechanism may be the shaft 18. The shaft 18 may be driven, within the skill of a mechanic, from the engine 11, but, in the present embodiment ofl the invention, the

shaft 18 is connected as indicated at 21, with an engine or motor 22 that is carried on the boom 12 nearto the butt end thereof.

The numeral 23 designates an'y arm mounted to move endwise and to swing vertically in the boom 12. The arm 23 is 'provided with. a rack 2,4 meshing with a pinio 2,5 carried by the shaft 16. i

There is a carrier for material, on the for- .ward end of the arm 23, and the carrier may be ofvarious sorts. As shown in Fi ure 1,

the carrier is in the form of adungork 26 including a head- 27. attached tov the end of n the arm 23, thehead carrying projecting tines 28.A v I The numeral 29 .marks va cleaner, including a body ,orl plate 30 mounted loosely for reciprocation and for tilting movement on the tines 28 of the` fork 26, the body ofthe cleaner being connected to a stem 31 which is pivoted at 32 to an operating member 33, in

the form of/ a bar, rthev operating member being mounted for .sliding movement in a guide 34 carried by the boom 12, the operat- 'lng member 33 being provided with a stop 35, adapted to cooperate-with the guide 34.

' On its lower edge and near its rear end, the

operating member 33 has a shoulder 35.

The shoulder 36 on the operating member 33 is adapted to cooperate with a cross bar 37 forming part of a stop frame 38, the stop ,frame including parallel bars which are adjustably connected at 39 to the boom 12, the

rear end of the stop frame 38 being carried by a suspension means of any desiredsort, for instance, a strong spring connected to thegguy '14, and, therefore, to the support 1.

A bail 41 is pivoted to the head 27 of the fork 26' and carries a sheave 42 about` which is looped a flexible element 43, one end of which is connected to the boom 12, the/flexible element being carried upwardly and rearwardly around a pulley journaled on the end of the boom 12, the flexible element being extended beneath a guide pulley 44 supported for rotation on the butt end of the boom 12, the flexible element 43 being wound. about the drum 8. v

The yoperating member 23 is moved endwise by a train of elementsI including the engine 22, the connection 21, the shaft 18, the connection 17, the shaft l.16, the pinion 25 and the vrack 24, the last-specified train of elements being under the governance of an operator by means of the reversing and stopping device 19Jand the lines 2O or their equivalent. The turntable 4 is rotated, and

the boom`12 is swung sidewise, by a train of elements deriving motion from thedrum 8, that train being under the control of an operator, by means of the clutch mechanism 9. and including the shaft 7, the 'worm v6 and 'the worm wheel 5. y

When the arm 23 is swung` upwardly and y carried rearwardly, the rear end of the operl thus, is brought' to rest,

ating member 33 comes into contact with the cross bar 37 of the stop frame 38, the said cross bar engaging the shoulder 36 on the operating member. The operating member, and the arm 23, carrying the fork 26 is carried rearwardly, with respect tothe body 30 of the cleaner 29, the body of the cleaner pushing the material olf the tines 28 of the fork 26, the parts a'rriving ultimately in the positionfshown` in A Figure 5, the stem 31 of the cleaner pivoting at 32 with -respect to the operating member 33. The stop 35,-,which'engages the'guy 34, prevents the body 30 of thel cleaner from sliding ofi' the tines 28 of the'fork26. The

spring 40 may be omitted if desired, but

when i'tJ is used,' it "will support' the rear' end of the stop frame 38 yieldably, and thus 'prevent undueV strains, should the inner end of the arm 23 continue to. swing downwardly for a `little while, operating member 33 has come into contact with the cross bar-37 of the stop frame. The carrier need not be in the formof a fork. In Figures 6 and 7, parts hereinbefore described have been designated by numerals previously used, the carrier being in the form of a scoop 46, and the body 30a of the cleaner 29a being mounted to move Withiny the scoop. r

is claimed is y l 1. In a device of the class described, a support, an arm mounted on the support vt0 y swing vertically and move longitudinally, means for swinging the` arm vertically, means for moving the arm longitudinally, a ,carrier and means for mounting the carrier on the support,- a cleanerislidable on the carrier, and means for arresting the movement of thecleaner when the arm is swung vertically -and moved longitudinally, thereby causing the cleaner to remove material from the carrier.-

2l. In a device of the class described, a support, an arm mounted'on the support, to swing vertically and to move longitudinally, means for swinging the arm vertically,

after the rearfend of the' means for moving the arm longitudinally,

' a carrier and means for mounting the carrier on the support, a cleaner slidable on the carrier, and astop frame wherewith a portion of [the cleaner cooperates, when the arm is swung vertically and moved longitudinally,

thereby causing the cleaner to remove mate;

rial from the carrier.

3. In a device of the class described, a support comprising a boom, an arm, means for moving the arm lengthwise on the-boom, means for'swinging the arm vertically on the boom, a carrier mounted on the boom, a cleaner slidable on the carrier, and means for arresting the `movement of the' cleaner when the arm is swung vertically and moved. lengthwise.v f

In testimony that I claim the vforegoing .as my own, I have hereto alixed my signatu're.
